High-performance assembly-type combined externally-hung wallboard

Abstract

The invention discloses a high-performance assembly-type combined externally-hung wallboard. A main body part of the high-performance assembly-type combined externally-hung wallboard can be divided into three layers, wherein a decorative layer is prepared of a colorful high-ductility cement-based composite material, a thermal insulation layer is prepared of foamed concrete, and a structure layer is prepared from lightweight ceramsite or baking-free light aggregate concrete, so that wallboard self weight is light. A wallboard and the main body part are connected through limit slippage nodes, so that influences of the main body part on the externally-hung wallboard in earthquake are reduced. The high-ductility cement-based composite material of the decorative protective layer is high in tensile strength, ductility, and is excellent in cracking controlling performance, and the color can be customized. Dovetail grooves are arranged at the interfaces of different layers, the layers of the wall body are connected through connecting components with forks and wings, so that wall body integral performance is improved. The connecting components are coated with FRP, so that wallboard heat bridge effect is reduced effectively. The high-performance assembly-type combined externally-hung wallboard possesses thermal insulation performance, energy saving performance, is high in weight, is high in strength, and is excellent in durability; wallboard decoration-thermal insulation-structure function combination is achieved; and the application prospect is promising.

[0001] Technical field: [0002] The invention belongs to construction engineering technology, and in particular relates to a high-performance assembled composite external-hanging wallboard and a method for connecting it to a structure. [0003] Background technique: [0004] Traditional building exterior walls are usually divided into several forms such as lightweight block exterior walls, concrete sandwich composite wall panels, and curtain walls (often made of glass, marble, and high-performance concrete, etc.). The exterior walls of lightweight blocks are mostly treated with external or internal thermal insulation.

AI Technical Summary

Problems solved by technology

The exterior walls of lightweight blocks are mostly treated with external or internal thermal insulation. Buildings with external thermal insulation treatment have higher requirements on the durability of thermal insulation materials and poor fire performance; It is easy to generate dew condensation and flooding, which will erode the wall itself, and the construction of the masonry structure itself is complicated, with many processes, and the labor cost is also relatively large, making it difficult to adapt to the needs of the development of the times

Concrete sandwich composite wall panels generally adopt the structural form of concrete + insulation layer + concrete. Due to the inherent brittleness of concrete itself, such as poor toughness, low tensile strength, weak impact resistance, easy cracking and difficult to control cracks after cracking, if the Ineffective control of the crack width not only affects the appearance of the exterior wall, but also causes structural durability problems and becomes a safety hazard

Curtain walls made of materials such as glass, marble, and high-performance concrete often have poor thermal insulation performance, and materials such as glass and marble are fragile and fragile materials that are more easily damaged than traditional materials during construction, installation, and use.
